steph, has your c seen you on an individual basis before?? if not s/he may not be open to talking to you alone as it effects the way s/he can treat you as a couple... some will some will not... I am not sure if your w is ready to hear you talk about the new sense of detachment you feel or even if she will believe it just yet. who generally leads the "feeling" in the c sessions? do you usually have to remind w of sessions... does she go to appease you the ole "I'm doing this just so we can get along to care for our children"
anyway without a whole lot of babble from me...if you feel you want to talk about these things with a c... I would suggest you get one of your own that is where you discuss you and your feelings, keep this one separate for the r talks. if wife still wants to or is willing to go to these sessions go and just talk about getting along...you don't have to outright say you are "detaching" or questioning your desire to work on the marital relationship it will just show in the way you are able to work at other things...remember actions speak louder than words..and reactions to the words of others are also actions that speak w no doubt see's your reaction changing... for now hush hush. LL do i make any sense?
